We report a case of mucinous cystadenoma of uncertain malignant potential and carcinoid of appendix associated with bilateral mucinous cystadenoma of ovary and pseudomyxoma peritonei. The patient was a 46-year-old female. She suffered from dyspnea and lower abdominal palpable masses for several months. Ultrasonogram showed multilocular huge ovarian cysts. Appendectomy, transabdominal hysterectomy, bilateral salphingo-oophorectomy and biopsy of omentum were performed. The bilateral ovaries measured 16 11 cm and 7X5 cm in size, respectively. The both ovaries showed multilocular cysts filled with thick mucus material. The ovarian cysts were covered by a single layer of columnar epithelium with focal proliferation. Mucus materials dissected through the ovarian stroma (pseudomyxoma ovarii). The tip of appendix was dilated and covered by mucus material. The cut surface showed a cyst and a yellowish solid mass proximal to the cyst. Microscopically, the appendiceal cyst was lined by stratified columnar epithelium with moderate cytologic atypia. Mucus material dissected through the wall. In the proximal portion of the appendix, a classic carcinoid with focal tubular form was present in submucosa and muscle layer. The omentum was covered by thick mucus material. Microscopically, the omentum showed mucinous epithelium and mucus material (pseudomyxoma peritonei).

Hyperkeratosis of the renal pelvis and ureter is a rare condition and is explained by the metaplastic change from transitional to cornified squamous epithelium. This lesion is frequently associated with, and perhaps caused by chronic urinary infection, but potentially premalignant, accompaning with carcinoma in about 10 to 20 per cent of the cases at the time of diagnosis. A case of hyperkeratosis of renal pelvis & ureter which was clinically suspected of carcinoma in a 49-year old woman with a long history of chronic pyelonephritis is presented with review of literature.

BACKGROUND: Direct observation of healthcare workers is commonly used in hospitals to investigate hand hygiene compliance. However, the hand hygiene compliance rate may increase due to the Hawthorne effect, which is the modification of behavior simply because subjects become aware that they are being observed. The objective of this study was to investigate the occurrence of the Hawthorne effect when directly observing hand hygiene compliance in intensive care unit (ICU) healthcare personnel. METHODS: A total of 87 staff members from the coronary care unit and cardiac surgery ICU of a general hospital in Seoul were included in this study: 24 residents and interns, 55 nurses, and 8 nursing assistants. Both covert and overt observations, where subjects were either unaware or aware of any direct observation, were performed on separate occasions. RESULTS: A total of 1,052 covert and 1,336 overt observations were documented over 30 and 34 occasions, respectively. Overall hand hygiene compliance was significantly higher with overt observation than with covert observation (1,041/1,336, 77.9% vs. 659/1,052, 62.6%, P<0.001). The Hawthorne effect was present in all professions and behaviors, with the exception of nursing assistants, and prior to touching a patient. CONCLUSION: Direct observation of hand hygiene compliance was associated with the Hawthorne effect when observations were made overtly and this was likely to contribute to an overestimation of compliance rate.

The purpose of this study was to investigate the difference of body composition, eating habits and dietary intake in three Sasang constitutions. This survey was carried out using anthropometry, a questionnaire about eating habits, and 24-hour recall of dietary intake on 45 male and 29 female students of the fifth grade at C elementary school. The results are summarized as follows: A total of 44.6% of the subjects were Taeumin, 35.1% were Soyangin, and 20.3% were Soeumin. The average weight, WHR, Triceps, Rhrer index and BMI in the Taeumin group were significantly higher than those of the Soeumin and Soyangin groups. The body fat mass (kg) and abdominal fat (%) in the Taeumin group were significantly higher than those of the Soeumin and Soyangin groups. The soft body mass (%) in the Soeumin group was significantly higher than that of the Soeumi and Soyangin groups. The Taeumin's energy expenditure in physical activities was little high than that of the Soyangin and Soeumin groups, but the Soyangin's energy expenditure in physical activities per weight was a little higher than that of the Taeumin and Soeumin groups. The calorie and most of the nutrient intake were lower than those of Korean RDA. In the case of males, most nutrient intake, except for fiber, carotene and vitamin C were high in the Taeumin. For females, most nutrient intake, except for calcium and retinol were significantly higher in the Taeumin group. Conclusively, anthropometry characteristics, body composition, energy expenditure in physical activities, eating habits and dietary intake are different among the three Sasang constitutions. This study suggests the possibility of using Sasang consitutions as a basis for providing nutritional education and health guidelines.

PURPOSE: This study was performed to measure hospital nurses' perceived patient safety culture and their safety care activities, and to investigate the relationship between these two factors. METHOD: This study was a cross-sectional survey. The participants were 301 nurses working at 4 general hospitals, and data collection was done from June 22 to June 30, 2009 by self-administrated questionnaires. RESULTS: With a possible score of 5 points, the average score for nurses' perceived patient safety culture was 3.34, and for their safety care activities, 4.25. There were perceived differences in patient safety culture and safety care activities according to age, position, length of work experience and number of patient safety education sessions attended. All sub-factors in patient safety culture had a positive relationship with safety care activities. Factors influencing nurses' safety care activities were number of patient safety education sessions attended, hospital environment, and supervisor/manager. These factors explained 58.2% of the variance. CONCLUSION: The findings indicate that patient safety education is very important to improve nurses' safety care activity. So nursing supervisors/ managers should develop strategies encourage patient safety education, and make nurses' working environment safer.

We experienced a case of adenocarcinoma arising in sacrococcygeal teratoma. The patient was a 52-year-old woman. She was admitted due to one month of sacral pain. She had a sacral mass since birth. On physical examination, anal fistula was present at the perianal area and pus drainage was noted. MR image showed multiple variable-sized cysts with inhomogeneous density. Resected specimen, mesuring 12.5 7.0 cm in diameter, showed multiple variable-sized cystic lesions admixed with grayish solid portion. The cysts contained mucoid material. The microscopic examination showed mature teratoma composed of cysts lined by pseudostratified ciliated columnar epithelium, intestinal mucosa, mature cartilage, bone, and fat tissue. A moderately differentiated adenocarcinoma developed from the cystic area in the mass.

Intraosseous lipoma is a very rare primary tumor of the bone. We report four cases of intraosseous lipoma. The patient ranged in age from 34 to 59-year-old (median age: 35 year-old). There were three men and one woman. All of four cases presented with pain. The involved bones were calcaneus in two cases, tibia in one case and ilium in one case, respectively. In all cases plain x-ray film revealed well-defined lytic lesion. Their size ranged 2 to 4.5 cm (mean size: 3.5 cm). Histologic examination showed mature adipose tissue. Three cases showed secondary changes such as atrophic bone, fat necrosis, fibrosis, dystrophic calcification, and reactive ischemic bone formation. The clinicopathologic and roentgenographic correlation are necessary in establishing correct diagnosis of this tumor.
